CLOTH-CUTTING- MACHINE.

Application filed September 19, 1916. I Serial No. 120,939.

To all whom it may concern Be it known that I, THOMAS SHINGLER,

a citizen of the United States, residing at ard by which the motor is supported from In cutting some 7 the base of the machine. kinds of material, such, for instance, as rubberoid, the knife becomes sticky or gummed by contact with the material, and this increases the friction of the knife in its guide to such an extent as'to greatly 1mpede the operation of the machine.

The object of the invention is to obviate this difliculty by providing machines of this kind with a lubricating device ofsimple and practical construction which will effectually lubricate the knife so as to prevent it from working hard in its guide.

In the accompanying drawings! Figure 1 is a fragmentary side elevation, partly in section on line 11, Fig. 2, of a cloth cutting machine embodying the invention.

Fig. 2 is a front elevation partly in section thereof, the knife being removed.

Fig. 3 is a side elevation, partly in section, of the lubricating device detached from the machine.

Fig. 4 is a sectional elevation on line 4-4, Fig. 2.

Fig. 5 is a sectional plan view on line 55, Fig. 4.

With the exception of the means hereinafter described for lubricating the knife and its guide, the machine may be of any suitable construction, and an electric cloth cutting machine of well known construction is illustrated in the drawings.

The machine has the usual base A adapted to rest and move on the cutting table beneath the material to be cut, a vertical standard B which rises from the base and supports an electric motor C, and a knife D which is reciprocated vertically by suitable driven connections E with the motor.

The knife, as usual, reciprocates in a vertical guide or slot F in the front edge of the standard B. In the. machine shown in the drawings, a hollow frame or housing G surmounts the standard B, being secured on a horizontal extension 9 of the upper end of the standard, and the motor C issecured onthisjframe G. Thelubricating means forthe knife and its guide are preferably constructed and arranged as follows: r

10' indicates a cup or reservoir mounted on one side of the housing Gr and adapted to contain a suitable Oil r liquid and feed the same in a suitably regulated manner to the knife. A sight-feed oil cup of ordinary constructionis shown having a drip nozzle 11 controlled by a valve whichcan be adjusted to cause the oil to drip at suitably regulated intervals, determined by the. adjustment of the valve. Theoil cup is se- Patented Mar. 6, 1917.

cured on a tubular connection 12 which is terminating so as to drip into a flaring groove or notch 17 in the upper end of the standard B and connectingwith the upper end of the knife guide. The oil dripping from the tube is thus directed into the upper end of the knife guide and effectually lubricates the same and the knife. By this arrangement the discharge end of the feed tubeis exposed at the front of the machine where the feed of the oil from the same can be readily seen and the tube can be easily cleared of an obstruction in the event that it should become clogged. The oil cup is located at the side of the machine where it will not interfere with the proper manipulation of the machine or obstruct the operators view of the work, and as the connection 12 is detachably secured on the frame the oil cup with the connected feed tube can be readily detached and removed when the machine is to be used on material which does not necessitate the lubrication of the knife.

I claim as my invention:

1. In a cloth cutting machine, the combination with an upright standard provided with a knife guide and a knife which recipro'cates in said guide, of lubricating means comprising a lubricant reservoir supported at one side of the standard'above the knife guide, and a feed passage leading from the reservoir and having its discharge end .arranged adjacent the upper end of the knife for lubricating the same.

2. In a cloth cutting machine, the combination with an upright standard provided with a knife guide and a knife Which recip- V rocates in said guide, of lubricating means comprising a lubricant reservoir supported at an inclination above the knife guide, a feed passage leading from the reservoir and having its discharge end exposed at the front of the machine, and a guide arranged to receive the lubricant from the feed passage and direct it to the knife.

3. In a cloth cutting machine, the combination with an upright standard provided with a knife guide and a knife which reciprocates in said guide, of lubricating means comprising a lubricant reservoir supported at an inclination above the knife guide, a feed passage leading from the reservoir and having its discharge end exposed at the front of the machine, and a guide groove in the upper end of the standard arranged to receive the lubricant from the feed passage and connecting with the knife guide.

4. In a cloth cutting machine, the combination with an upright standard provided with a knife guide and a lubricant guide channel in its upper end connecting with the knife guide, and a knife which reciprocates Copies of this patent may be obtained for in said guide, of a lubricant reservoir sup ported at an elevation above the knife gulcle, and a feed passage leading from the reservoir and having its discharge end exposed a:

elevation above the knife guide, and a feed tube leading from the reservoir and arranged to discharge the lubricant to the knife guide, said reservoir and feed tube being detachable as a unit from the machine.

6. In a cloth cutting machine, the combination with an upright standard provided with a knife guide, a frame mounted on the standard, and a knife which recpirocates in said guide, of lubricating means comprising a lubricant reservoir detachably mounted on one side of said frame, and a feed tube leading from the reservoir through said frame and arranged to discharge the lubricant to the knife guide, said reservoir and feed tube being connected and detachable as a unit from the machine.

Witness my hand, this 16th day of September, 1916;

THOMAS SHINGLER.
